Re: c++ classes in lua

[Johannes Hager <hager.j@...>]

Hi,

i try to use lua. But if i do:
	luabind::open(L);
it brings a linker error. So if i do it with lua_open(L) all works, but if i 
try to luabind::function(L, "sin", &std::sin) that comes:
	
/tmp/ccYmyESX.o(.gnu.linkonce.t._ZN7luabind6detail17function_commiterIPFvvENS0_9null_typeEE6commitEP9lua_State+0x2bb): 
In function `luabind::detail::function_commiter<void (*)(), 
luabind::detail::null_type>::commit(lua_State*)':
: undefined reference to 
`luabind::detail::free_functions::function_dispatcher(lua_State*)'
collect2: ld returned 1 exit status
